So if we write out every term individually, what we end up with is essentially just the probability density for the first atom, then the probability density for the second atom, and then we have this last term here, and this is what ends up being the interference term.

如果我们把每一项都写出来，最后得到的就是,第一个原子的概率密度，然后是第二个原子的概率密度，然后是这最后一项，这就是干涉项。
